So, after further discussions, we came to the conclusion that the system would be better for her car. I already have two GPS's, one handheld (GPSMAP 60cs) and one no-name brand 7" windshield mounted one. Also, the RF system that comes with the SE should fit my needs.
The deal was, she can have the AVIC-Z2 if I can get a factory satellite addon for the X.
I went to look up prices on them, and they want $336.49 for the satellite receiver. That's dollars, not pesos or yen. Is there any other place to get one of these? That price is ridiculous.
I sent an email to Brian Cadigan over at Nissan of Turnersville about one on their site, but that is marked for Frontier. I'm waiting to hear if it fits the RF in the X.
